Draftsi'nen making shop drawings, workof various kinds have occasion torepeatedly draw circles, T-unions, elbows-etc, in tne course of acomplete drawing and much time is lost bydrawing the same thing over andover. To speed up this n g may be made in stock stamps which areinterchangeably fitted in the end of the tool and then instantly appliedto the drawing. At the same time the tool is provided with acompass-carrying attachment or bracket which permits instant use ofeither the tool as a stamp or center finner or marker, or of thecompass. p

The tool comprises tubal; r body portion 1 threaded interiorly at bothof its open ends, one end receiving a threaded cap orplug 2 and theother a stainp il threaded as shown, the stamp being perforatedvcentrally and forming a closure for the body. The outer face of thestamp 8 carries the impression of a circle, elbow or like figure whichmay be readily impressed upon the work in a manner to be hereinafter setforth,

The body 1 is formed with a contracted portion 4 provided withdiametrically'opposed longitudinal slots 5, 5 and with an annular groove6 spaced from said contracted portion. A nut 7 threaded and perforatedcentrally and longitudinally is formed with a surface groove 8 toreceive the'end of a screw driver and is removably fitted into the vream rare or CHICAGO, ILLINOIS.

'lhe spring 18 will yieldingly'thrust the pointed end of the pin 9beyond the adjacent end of the body 1 and in this position the pin maybe used as a marker. When a slight blow by hand is administered to thestamp. A colnear its'lower and collar 12is loose cap 2,however, thespring 13 will be 'con- I tracted, the pin retracted and the stampcaused to register its impression upon the work. I

A bracket comprising ashort bar 14 and a long bar 15 connected by legs16 isprovided,

said bars being formed with diametrically opposed perforations 17 andthe bar-15 formed with a terminal notch 18, said bracket being adaptedfor disposal in the slotte'dport-ion 5 of the body 1 the bracketperforations 17-receiving the pin 9"whereby said bracket is retained inposition.

One leg 190i a compass is fitted to the notched end of the bar 16 andsecured in p0- ition by thethumb screw 20,- the other leg 21 being thenad usted and used to mark centers, measured distancesor spaces etc.Dista nces from the pointed end 10 of the pin 9v to the marking end ofthe leg 21 can be read-' ily marked off, the compass being manipulatedby the bracket and tool body grasped by hand.

What is claimed is I 1. In a markingand stamping tool, a tubular bodyhaving a contracted portion, a

stamp in one end of'said body, a pin extending longitudinally of saidbody and stamp, a collar fast uponsaid pin, a collar loose upon said pinfor engagement with a contracted portion of said body, and a springencircling said pin and connecting said. collars.

2. In a marking and stamping tool, a tubular body, a sta n 'o in one endof said body, a

pin extending longitudinally of said body and stamp, a collar fast uponsaid pin, a

. collar loose upon said pin, the movement of said loose collar in onedirection being limited by the said body, anda spring encircling saidpin and connecting said collars.

3. In a Inarking-andstamping tool, a. tubular slotted'body portion, apin extending through said body portion, and a bracket arranged inthe-slotted portion of said body and perforated to receive saidipim saidbracket being notched to receive one leg of a compass.
